The purpose of the Mars 2018 Sky Crane Capabilities Study was to "explore the full range of science capabilities that could be delivered to the surface of Mars in 2018 by an MSL-derived Sky Crane EDL system" . NASA commissioned the Jet Propulsion Laboratory (JPL) to perform this study. The Planetary Science Decadal Survey Mars Panel was particularly interested in the following science pathways: a surface field geology/astrobiology pathway, a subsurface geology/astrobiology pathway and a network science pathway. There was also an interest in examining mobile and non-mobile options. The key trades in this study involved various combinations of mission elements for the three science pathways and the choice of a mobile versus fixed option.
